The present invention'relates to carbureting and lubricatlng devices for internal-combustion engines; and its object is, generally,

to provide a device of this character improved fr in various respects hereinafter appearing;

, tion and a second carburetor whereby a luand more particularly, to provide in combinatlon acarburetor of usual type and opera bricant with heated air may be drawn into the manifold common to both carburetors; and further, to provide in such a device means whereby the vacuum in the engines intake manifold may be decreased; and further, to provide in connection with said second carburetor means for relieving the vacuum occasionedby the drawing of an insuflicient amount of lubricant therethrough; and further to provide in such a device means whereby the gases in the engines crank case may be drawn into the engine and utilized as fuel; and further, ling the said also in their interrelative, operations; and further, to provide such a double-carburetor device whereby increased economy at high speeds ma be attained. Y

These objects are attained by, and the inventionfinds preferable embodiment in, the

structure hereinafter particularly described in the body of trated by the which: a

Figure 1 is a side view of an internal-combustion engine having my carburet-ing and lubricating device applied thereto Figure 2 is a top plan view of said device; Figure 3 is an end-view of the same; Figure 4 is a side view of the manifold common to both the carburetors of the device; and

Figure 5 is a view of a flexible tube where this specification and-illusaccompanying drawings, in

by heated air and lubricant is drawn into one the fuel of the carburetors.

' In the embodiment of the invention illustrated by said drawings, my carbureting and lubricating device is shown applied to the side of an automobiles internal-combustion engineof any usual type. The manifold 1 vents into the engine through the ports 17 and 18, and air mixture being drawn into to provide means forcontrolcarburetors in their joint, and: 'pling T, and into tical post 28 and has a the manifold through its port 16 from the first carburetor 2 and the fuel, air and lubricant mixture being drawn into the manifold through its port from the second carburetor 3. The first carburetor 2 is of usual type and operation, air being drawn thereinto through the pipe 37 connected to said carburetor at w. The lubricant-i. e., oil fumesis drawn into the second carburetor 3 from a suitable source as the engines crank case; through a flexible pipe 5 supported at s in proximity to the engine (as by a collar 21 detachably secured by a bolt 36) in order that the air and lubricant passing therethrough may be heated by the engine. This pipe 5 has a portion 6 provided with air intakes through its wall, so that any vacuum created by the operation of the engine may be suiliciently relieved. The fuel is delivered to both carburetors through a pipe 4 venting into the first carburetor 2 through the couthe second carburetor 3 through the elbow d. The passage of the fuel and air mixture through the first carburetor 2 is controlled by a valve whose shaft 38v has an operating arm 8, the passage through the second carburetor 3 being controlled by a valve whose shaft 39 has the operating arm 11. Suitable connections for operating these valves jointly and also relatively to each other are provided such connec tions (as illustrated) being the following: An annular element, the flexible band 27 may be clamped in angularly adjusted position around the second carburetor 3 as by the screw bolt 29. This band carries a verlateralextension in whose bearing 24 a vertically disposed rock shaft ".7 turns. When the arm 8 of the-first carbur'etors valve is swung, by a suitable 99 operating rod indicated at 30 in dotted lines, a far enough toward the left-hand side of Figure 2, it strikes the'lower crank arm of shaft 7 turning it in its bearing 24 and causing its upper crank arm to swing the short ation ofthe operating rod 30 moves both valves together toward their open positions,

such movement of arm 11 being yieldingly resisted by a spring 13 connected at one end to said arm and at the other end to a bracket 14 at J, said spring pressing this valve to closed position.-

It will be seen that the interrelative move- I ment of these valves may be adjusted by turning theiband 27 about the second carburetor 3 to desired clamped position. Thus the band 27 may be turned and clamped in such a position that the lower crank arm of shaft 7 will not be contacted and swung by arm 8 until the valve of the first carburetor 2 is half open, and nevertheless the valves of both carburetors may be completely opened at the same time.

It will be seen air mixture passing through the first carburetor'2 and the amount of heated air, fuel and lubricant mixture passing through the that the amount of fuel and mediate point betweenthe high speed carbureter and the crank case with apertures communicating with the atmosphere and adapted to decrease the vacuum of the engine, controlling means for the main carbureter, and separate controlling means for the high speed 'ca'rbureter automatically operable by the first mentioned controlling means when the engine has attained a predetermined speed.
